LIQUID COMPOSITION FOR LAOQ'O'ERING PURPOSES.

No Drawing.

To all whom it may concern:

Be it known that We, OTTO SCHMIDT, THE- ODOR EICHLER, and O'r'roALLEMANN, citizens, respectively, the firsttwo of the German Empire andthethird 'of'the Swiss Republic, residing, respectively, the first andthird at Ludwigshafen-on-the-Rhine and the the owing is a specification.

. carbon atoms 1n the ring. Oyclo-pentanone, cyclo-hexanone andhomologues of these other atMannheim, Germany, have invented new anduseful Improvements in Liquid Com positions for Lacquering Purposes,

Our invention has reference to newcompositlonsofmatter 'whlch' areliquid solutions able of use forlacquering purposes and arecharacterized by containinga monocycllc ketone possessing either five ors1x compounds may be mentioned as instances of cyclic ketones which canbe employed according to this invention and they are very suitable foruse as solvents for nitrocellulose and resins because theypossessvaluable solvent properties and; also evaporate with suchvrapidity thatthe nitrocellulose, or the resin,

is left as a firmly adhering transparent skin.

The cyclic ketones are not so :dangerous in use as, for instance,inflammablev acetone and benzene, and the solutions are conse-. quentlyexcellently adapted for use in the lacquering industry .for producingpolishes,

. lacquers and the like. We have also found that solutions can beemployed which contain' other liquids, in particular. hydrocarbons, suchfor instance as benzene, ligroin.

may be desired to dissolve,'the additional solvent-and the quantitythereof may be advantageously yaried. Such lacquers are characterizedboth by their cheapness and 'by the fact that they dry more quickly thanthose obtained with a cyclic ketone without such addition of solvent.The cyclic ketones further have the advantage that they dissolve manycoloring matters, so' that 001-:

ored solutlons can be obtained; the aforesaid cyclic ketones can also beused for re- I Specification of Letters Patent. 1

moving nitrocellulose or-resins by dissolvmg them away from any ObJGCtas desired. The lacquers containing one or more cyclic ketones, ashereinbefore set forth, may also contain other ingredients, such .as areor may be used n the manufacture of lacquers- The followlng exampleswill serve to illusfeet, but the vinvention is not confined to lulose in100 partsof cyclo-hexanone. A lacquer is obtained which plication toWood, like. j I

Example-2: Dissolve 1 part of'nitrocellu lose in 50 parts ofcyclo-hexanone and add 50 parts of ligroin. .The solution obtained issuitable for appolished metal, and the n is suitable for lac uering bydipping the article into the solu ion.

Example 3: Dissolve5 parts of nitrocellu I lose in 100 parts ofcy'clo-he'xanone. This.

solution is suitable forfastening pieces of celluloid together.

Example 4.: Dissolve 20 parts of dammar m 60 parts of cyclo-hexanone,whereupon a solution is obtained which can be used for lacquering.- Ifdesired, linseed oil can be added to the lacquer to reducethebrittleness of the skin obtained.

Instead of dammar, copal, or pine resin, can be: employed, or othersuitable resins can be m e use of.

In asimilar manner, solutions for other purposes of the lacquerindustry, or for. analogous purposes, can .be obtained and, in b asimilar manner, homologues of cyclo-hexanone, or a mixture ofcyclo-hexanone and one or more, than one'homologue thereof canbeemployed. If'desired, other solvents, or diluents, can-be employed atthe same time as the'cyclic' ketones and, if desired,-other suitableadditions may be made.

Now what we claim is 1: Asa new composition of matterwhic'h I v issuitablefor lacquering purposes, a liquid solution containinga-monocyclic ketone possessing more than four and less than seven carbonatoms in the ring.

2. As a new composition of'matter which is suitable for lacqueringpurposes, a 1i uid solution containing nitrocellulose an a and how itcan be carried into practical of monocyclic ketone possessing more thanfour and less than seven carbon atoms in the ring.

3. As a new composition of matter which is suitable forlacqueringpurposes, a liquid solution containing nitrocellulose, ahydrocarbon and a monocyclic ketone possesslngis suitable for lacqueringpurposes, a liquid solution containing nitrocellulose, methyl i5cyclohexanone and benzene.

In testimony whereof we have hereunto set our hands in the presence oftwo subscribing witnesses.
